Abstract
Urban roundabouts are always implemented in order to represent the urban environment and traffic calming in cities. But with the increase in traffic flow rates as a result of the development of cities, they have sometimes lost their function. On the other hand, in many cases during off-peak hours, due to poor geometric designs of the roundabouts, drivers tend to exceed the speed limit, which in turn increases the number of pedestrian accidents in these roundabouts. Rasht, one of the most populous cities in northern Iran, has more than 20 roundabouts, and on the other hand, the number of pedestrian accidents in this city is very high. Therefore, in this study, using accident data from 2018 to 2021, the factors affecting pedestrian accidents in the urban roundabouts of Rasht city were investigated. The results of accident analysis using the Friedman test showed that the variables of accident reason, pedestrian gender, and driver age had the highest rank in the occurrence of pedestrian accidents in urban roundabouts. In addition, according to the factor analysis, the variables of lighting condition, road surface condition, and weather condition were under the first factor in pedestrian accidents in urban roundabouts. Therefore, human and environmental factors had the most significant impact on the occurrence of pedestrian accidents in Rasht urban roundabouts.
